FERDINAND MUHL, OF PITTSBURG, PENNSYLVANIA.

CARPET-SEATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 788,117, dated September 1, 1903.

Application filed May 29, 1902.

To all whom it may concern.-

Be it known that I, FERDINAND MUHL, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Carpet-Beating Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in carpet-beating machines, and has for its object the provision of novel means whereby a carpet may be thoroughly beaten, brushed, and cleaned.

The presentinvention furthercontemplates to provide a device wherein any width carpet, rug, or other fabric may be easily secured and readily cleaned.

Another object of this invention is to provide a device that will be extremely simple in construction, strong, durable, comparativelyinexpensive to manufacture, and highly efficient in its use.

IVith the above and other objects in View the invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part ofthis specification, and wherein like numerals of reference indicate like parts throughout the several views, in which Figure 1 is a top plan view of myimproved carpet-beater. Fig. 2 is a side elevation thereof, showing pulley A removed and shaft 5 in action. Fig. 3 is an enlarged perspective View of one of the clamps. Fig. 4 is a side elevation of one of the cams for tripping and operating the heaters.

In the drawings the reference-numeral 1 indicates the rectangular frame, having inclined sides 2, which are supported by standards 3 3, connecting the frame portion 1. A driven pulley 4, mounted upon the drive shaft 5, is secured in suitable bearings 6 6, arranged upon the frame. Upon the opposite end of the drive-shaft 5 is secured a pulley 7. Upon this drive-shaft 5 are also secured at suitable intervals sprocket-wheels 8, over which pass endless sprocket-chains 9. These sprocketohains pass over cog-pinions 10 10, which are Serial No. 109,446. (No model) correspondingly secured upon shafts 11 ll, journaled in the standards 3 3 and extending the entire width of the machine. Theendless sprocket-chains thence pass over a series of sprocket-wheels 12, secured upon theshaft 14, which is mounted in standards 15. Upon this shaft is also keyed cog-wheel 16, which meshes with similar cog-wheel 17, secured upon the shaft 18, which is likewise arranged in bearings formed in the standards 15. This shaft 18 also carries a series of cams 19, which are preferably formed in two sections and are secured together by means of bolts 20, these cams 19 being so arranged as to engage the ends 21 21 of the heaters 22, the latter being secured upon a shaft 23, which is secured in suitable bearings 24 of the frame. Springs 25 encircle the shaft and have their ends socured thereto and form a yoke 26, which normally presses the boaters downwardly against the carpet 27, which is secured by means of clamps 28, carrying the hook end 29, the latter being secured in one of the links of the sprocket-chain. Thecarpet27passesoverthe rotary brush 28, which is mounted upon the frame, and passes under the rotary brush 29, which is likewise mounted and is arranged above the brush 28, said brush 29 being driven by means of the pulley 30, which is mounted upon the shaft of the brush 29, and rotary movement is imparted to the pulley 30 through the medium of the belt 31, passing over the pulley 7and 30. Upon this pulley 30 is also arranged a belt 32, which passes over the pulley 33, mounted upon the shaft 18, for the purpose of communicating a rotary movement to the cams 10. For the purpose of preventing the carpet while being rotated from having an undue downward movement a series of wire rods 2, having hooked ends 3, are secured, respectively, over the shafts 11 and 5, the hooked ends freely engaging over said shafts, so as not to interfere with the rotary movement of the latter. In order to secure the wire rods in their respective positions with relation to the several shafts before mentioned, the shafts are preferably provided with circumferential grooves, in which play the hooked ends 3 of the wire rods,

which effectually prevents any lateral movement of the rods.

The operation of my improved heater is as follows: Power being imparted to the driven pulley 4, communicating a rotary movement to the drive-shaft5, carrying the sprocket- Wheels 8, whichin turn operates the series of endless sprocket-chains 9, the carpet being secured to the clamps 28, which are attached to the sprocket-chains, the same will be carried forwardly bet-ween the brushes 28 and 29 and thence to the heaters, which Will beat the carpet by means of the cam lifting the heaters, the latter being forced downwardly by means of the springs 25 upon the carpet. The carpet is thus allowed to pass through the machine a number of times until it has been thoroughly cleaned.

The above illustrates a practical embodiment of my invention, though it is obvious in constructing the same various changes may be made .both in the details of construction and combination of parts without departing from the general spirit and scope of the invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A carpet-beating machine, comprising a frame having a series of shafts carrying sprockets mounted thereon With endless chains passing over the sprockets, and rods having their ends bent to engage the shafts for supporting the carpet against downward movement, a series of heaters operating above the chains with means for operating the beaters, a brush operating on one side of the carpet and a second brush on the under side thereof, With means for operating the upper brush, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

FERDINAND MUHL.
